A first through hole 343 is opened in the surface of the inner sleeve 8. A second through hole 344 is opened in the surface of the cover body 4. The air enters the second through hole 344 through the first through hole 343. A cavity 345 is opened in the inner wall of the cover body 4. A third through hole 346 is opened in the surface of the annular ring 5. Finally, the air enters the inside of the cover body 4 through the third through hole 346 to support the secondary combustion of the heat in the cover body 4. The number of third through holes 346 is several, so that the overall heat utilization rate of the stove is high, and the harmful gas discharged by the stove smoke is greatly reduced. Among them, the external air enters the pipeline 342 through the air inlet 341 in the bottom of the shell 1. The air enters the second through hole 344 through the first through hole 343. Then it enters the cavity 345. Finally, it enters the inside of the cover body 4 through the third through hole 346 to support the secondary combustion of the heat in the cover body 4, so that the overall energy saving of the stove is more;

[0028] In the specific implementation process, it is particularly worth pointing out that when the charcoal inside the cover 4 is burning, the external air enters the pipeline 342 through the air inlet 341 at the bottom of the shell 1, and then enters the second through hole 344 through the first through hole 343, and finally enters the inside of the cover 4 through the third through hole 346, which is used for secondary combustion of the heat inside the cover 4.

The whole stove is more energy-saving;

[0031] Specifically, firstly, the worker adds firewood to the inside of the cover 4 and ignites it, generating heat. At this time, outside air enters the pipe 342 through the air inlet 341 at the bottom of the outer shell 1, then enters the second throughlet 344 through the first throughlet 343, then enters the cavity 345, and finally enters the inside of the cover 4 through the third throughlet 346, providing secondary combustion support for the heat inside the cover 4. The worker opens the firewood adding door 11 and puts firewood into the inside of the cover 4 through the first opening 41 and the second opening 81. After that, the worker closes the firewood adding door 11. When the cover 4 is damaged, the worker rotates the cover 4. At this time, the cover 4 drives the locking pins on both sides. Rotate 31, and the locking pins 31 on both sides move in the horizontal groove 33 in the inner sleeve 8. Rotate the locking pins 31 to the position where the horizontal groove 33 connects with the vertical groove 32. The bottom of the vertical groove 32 is connected to the horizontal groove 33. Then, the worker moves the cover 4 upward. The cover 4 drives the locking pins 31 to move in the vertical groove 32. Finally, the locking pins 31 are moved out of the vertical groove 32 and the inner sleeve 8 in the cover 4 is removed. The worker puts the new cover 4 into the inner sleeve 8. The locking pins 31 on the new cover 4 first move along the vertical groove 32 and then along the horizontal groove 33. Move the locking pins 31 on the new cover 4 to the end of the horizontal groove 33 and fix the new cover 4. Align the first opening 41 on the cover 4 with the opening 81 on the inner sleeve 8.
